Average Speed

As a runner completes a lap of a running track we can calculate his average speed from the distance round the track and the time taken to run round. During the lap his speed will vary and average speed calculation will gives the average value of his speed. The average speed play an important rule when the speed is not uniform.

In case speed is not uniform, we obtain average speed by dividing the total distance covered by the total time taken. In this section we will learn more about average speed.

The velocity of an object is defined as the displacement divided by the time internal during which the displacement occurred. Since displacement is a vector quantity, average velocity is also a vector quantity.
